title: [Nailfold capillaroscopy. Comparison of 100 subjects over 65 years of age and of 100 young adults].
abstract: Nailfold capillary microscopy patterns in 100 patients aged more than 65 years and free from inflammatory diseases were compared to those of 100 young healthy adults. A higher prevalence of arteriovenous sludge (36% vs 7%, p less than 10(-6)), increase in capillary loop length (12% vs. 0%, p less than 10(-3)) and especially prominent subpapillary plexus (63% vs 12%, p less than 10(-9)) was found in the geriatric group. Such capillary patterns cannot be considered as abnormal in patients aged more than 65 years. Enlargement of capillary loops and loss of capillaries were never encountered. Bushy capillary formations and hemorrhages were very uncommon in both groups.
